41 * @file
42 * @brief Interface Input Mode (Layer 2 Cross-Connect or Bridge / Layer 3).
43 *
44 * This file contains the CLI Commands that modify the input mode of an
45 * interface. For interfaces in a Layer 2 cross-connect, all packets
46 * received on one interface will be transmitted to the other. For
47 * interfaces in a bridge-domain, packets will be forwarded to other
48 * interfaces in the same bridge-domain based on destination mac address.
49 * For interfaces in Layer 3 mode, the packets will be routed.
